My bad. Comment on Nico Movie mentioned Kr server receiving an item that makes equipment go away, so I assumed it was the kit.
So, that'll make Japan the involuntary open beta tester of the kit ><
(happened with Ninjutsu as well)

I've been thinking about that same idea of equipment swapping for awhile now since I main Gunslinger and use bard skills but I also like to use alchemy so its very troublesome to switch all the equips since some get lost on my inventory. Good to know someone had readed my mind since I could just swap to alchemy equips (cressida, alchemy enchanted/reforged hats, and accs) to gunslinger equips without much effort.
